Overview
Evan Hubinger is one of the most influential researchers working on technical AI alignment, known for developing foundational theoretical frameworks and pioneering empirical approaches to understanding alignment failures. As Head of Alignment Stress-Testing at Anthropic, he leads efforts to identify weaknesses in alignment techniques before they fail in deployment.
Hubinger's career spans both theoretical and empirical alignment research. At MIRI, he co-authored "Risks from Learned Optimization" (2019), which introduced the concepts of mesa-optimization and deceptive alignment that have shaped how the field thinks about inner alignment failures. At Anthropic, he has led groundbreaking empirical work including the "Sleeper Agents" paper demonstrating that deceptive behaviors can persist through safety training, and the "Alignment Faking" research showing that large language models can spontaneously fake alignment without being trained to do so.
His research has accumulated over 3,400 citations, and his concepts—mesa-optimizer, inner alignment, deceptive alignment, model organisms of misalignment—have become standard vocabulary in AI safety discussions. He represents a unique bridge between MIRI's theoretical tradition and the empirical approach favored by frontier AI labs.
